That the message "map invalid" is being displayed, can have several causes, which are often difficult to assess.
In this case, we recommend checking the mowing zones as well as the no-go zones and adjusting them afterwards if necessary.
Example No-Go Zone:
Hint:
Make sure that the no-go zone includes the entire area (A) that the robotic lawnmower should not drive on.
Don't create a no-go zone (B) over the mowing area to prevent the robotic lawnmower from getting into certain areas.
If this measure is not successful, we recommend checking the virtual boundary in the GARDENA smart app and, if necessary, adjusting it slightly afterwards. To do this, the robotic lawnmower must be connected to the smartphone/tablet via Bluetooth.
If you still see the message "map invalid", we recommend deleting the map and recreating the virtual boundary.
